Description

Technical Field

[0001] This utility model relates to the field of clearance measurement technology for trackside equipment in electrical engineering, and specifically to a clearance measuring instrument for trackside equipment in electrical engineering. Background Technology

[0002] The autumn inspection work aims to improve the operational quality of signaling equipment and eliminate substandard equipment. It focuses on the inspection of ground and onboard signaling equipment (hereinafter referred to as signaling equipment), with particular emphasis on electrical characteristic calibration testing, gauge measurement and verification of rail insulation joints. The work is carried out under the principle of simultaneous inspection and rectification. The scope of the autumn inspection includes trackside signaling equipment on state-owned railways, joint-venture railways, local railways under contract maintenance, and dedicated railway lines, involving a massive amount of testing work.

[0003] There are many types of trackside signaling equipment, some high and some low, and their clearance dimensions also vary. As the track settles and other factors occur, the track position will constantly change during operation, thus affecting the clearance dimensions of the trackside equipment. Severe over-limits may lead to safety accidents such as vehicle scraping, passenger personal injury, or even collisions.

[0004] Currently, the measurement method for trackside clearance of electrical equipment is manual, using a steel tape measure. Since the measurement distance is typically 2-6 meters, the steel tape measure deforms after being unfolded. Furthermore, the lack of means to ensure the tape measure is horizontal or vertical leads to significant measurement errors. The measurement also requires multiple people, making it cumbersome and inefficient. Additionally, because the measuring tape is long and soft when unfolded, it is prone to bending and tipping due to improper use or wind, posing a potential risk of short circuits in track circuits and contact with the overhead contact line. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of the prior art by providing a trackside clearance measuring instrument for electrical engineering equipment. By configuring a single-axis gimbal and related devices on the base crossbar, it enables rapid and accurate measurement of trackside clearance for electrical engineering equipment.

[0006] The objective of this utility model is achieved through the following technical solution:

[0008] The single-axis gimbal includes a rotation mechanism, a single-point laser, a rotation mechanism knob, and an angle encoder. The rotation mechanism and the rotation mechanism knob are connected to the single-point laser and can control the rotation of the single-point laser. The angle encoder is coaxially mounted on the side of the rotation mechanism.

[0009] The single-axis gimbal also includes a signal light, which is connected to the control and display module.

[0010] The control and display module includes screen buttons and a control board. The screen buttons are connected to the control board, and the control board is connected to the single-axis gimbal signal to collect data.

The battery is used to supply power, the battery display screen is connected to the battery to display its power level, the switch is used to turn the battery on and off, and the SIM card transmits the data of the single-axis gimbal to the outside world via the antenna using 4G transmission.

[0012] The base crossbar includes a rod, a distance sensor, an inclination sensor, and a distance measuring baffle. The distance sensor is mounted on the rod to measure the track gauge, the inclination sensor is mounted on the rod to measure the angle between the rod and the horizontal ground, and the distance measuring baffle is located at both ends of the bottom of the rod.

Screen and button, 7. Distance sensor baffle, 8. Tilt sensor, 9. Battery, 10. Battery display screen, 11. Antenna, 12. Switch, 13. SIM card, 14. Bottom connector.

[0019] Example: Figure 1 and Figure 2 As shown, the trackside clearance measuring instrument in this embodiment includes two parts: a measuring instrument module and a base crossbar. The measuring instrument module mainly performs the function of measuring the clearance of trackside equipment, while the base crossbar serves to support and mount the measuring instrument module and assist in the measurement.

[0020] Specifically, the measuring instrument's measuring module includes a single-axis gimbal, a control and display module, a battery module, and a bottom connector; the base crossbar consists of rods, a distance sensor, an tilt sensor, and a distance transmission baffle.

[0021] The single-axis gimbal includes a rotating mechanism 1, a single-point laser 2, an indicator light 3, and a rotating mechanism knob 4. The single-point laser 2 is mounted on the single-axis gimbal and measures the straight-line distance to the target position. The rotating mechanism 1 is used for coarse adjustment of the angle of the single-point laser 2, and the rotating mechanism knob 4 is used for fine adjustment of the angle of the single-point laser 2. In this embodiment, the rotating mechanism 1 can be connected to the single-point laser 2 using a common hinge connection. For example, the rotating mechanism can be a rotating shaft connected to the housing of the single-point laser 2, allowing the single-point laser 2 to rotate under the drive of the rotating shaft. The rotating mechanism knob 4 can also use a common knob fine-tuning method.

[0022] In this embodiment, an angle encoder is coaxially mounted on the side of the rotating mechanism 1 to measure the angle rotated by the single-point laser 2. An indicator light 3 is used to display the working status of the single-axis gimbal. A bottom connector 14 is provided at the bottom of the single-axis gimbal. This bottom connector 14 is connected to the base crossbar via contact points, allowing for the disassembly and reassembly of the measuring instrument module and the base crossbar for easy use.

[0023] The battery module consists of a battery 9, a battery display screen 10, an antenna 11, a switch 12, and a SIM card 13. The battery display screen 10 displays the battery level, and the SIM card 13 is located within the battery module. It transmits the measurement data of the single-axis gimbal via the antenna 11 using 4G, for example, to a cloud server for further data processing.

[0024] The control and display module is the core of the device's control, including a control board, a screen, and buttons. The control board collects sensor signals, performs calculations, and displays the measurement data on the screen. Users can also operate the buttons to execute corresponding commands, perform distance measurement, and store and retrieve data.

[0025] The base crossbar consists of a rod, a distance measuring sensor 5, an inclination sensor 8, and a distance measuring baffle 7. The rod is the structural support of the system. The distance measuring sensor 5 is housed within the rod and is used to measure the track gauge. The inclination sensor 8 is a single-axis inclinometer, installed within the rod, and is used to measure the angle between the crossbar and the horizontal ground. The distance measuring baffle 7 is flush against the rail to keep the distance measuring instrument perpendicular to the rail.

[0026] In this embodiment, an elastic structure can be further provided on the ranging baffle 7 to give it a certain thrust to keep the ranging instrument perpendicular and in close contact with the rail.

[0027] Combination Figure 1 and Figure 2 As shown, this embodiment includes the following process when in use:

[0028] Upon initial use, a calibration platform needs to be set up to calibrate the sensors of the measurement system. This trackside equipment clearance measuring instrument measures the clearance of trackside equipment according to the following steps: the measurement result of the trackside equipment clearance measuring instrument is the clearance value of the trackside equipment.

[0029] When put into use, the measuring module of the measuring instrument is connected to the base crossbar through the bottom connector 14 via the contact point. The base crossbar is kept perpendicular to the rail. After powering on, the single-axis gimbal is rotated to align the single-point laser 2 with the electrical trackside equipment being measured. The angle is coarsely adjusted by rotating mechanism 1, and then finely adjusted by rotating mechanism knob 4. The control board automatically calculates the measurement results and displays the results on the screen. Data is recorded by clicking the button.

[0030] Repeat the above steps to complete all location measurements.

[0031] In this embodiment, the battery 9 is powered by a built-in high-capacity lithium battery pack, with a maximum continuous working time of 8 hours. It is suitable for measuring the clearance requirements of trackside electrical equipment in various environments. It has reliable electrical protection devices, a simple overall structure, convenient and quick measurement process, safe and reliable operation, and high cost performance.

[0032] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
